BRACKET FOR ELECTRIC LAMPS AND THE LIKE.

Specification of Letters Patent.

Patented J an. 4,1916.

To all whom it-may concern.'

Be it known that I, THOMAS D. FINIZIO, a

' subject of the King ofv Italy, residing atv New York city, BronX county, State of New York, y

have invented certain new and useful Improvements in Brackets for Electric Lamps and the like, of which thel following is a full, clear, and exact description.

This invention relates to an improvement in lamp-brackets or the like, the object .of the invention being to provide a bracket for electric lamps, fans, telephones, etc., with a rotatable self-winding reel to carry a twowire cable for conducting electric current to the current-consuming device carried by the bracket.

A further feature of the invention consists of a. novel arrangement of contacts or connections by which means the current is conducted from the cable to the lamp, fan, or telephone on the bracket, the saidA connections being arranged to permit of the movement of the cable, when wound or unwound,

` without breaking the electrical circuit.

Further features 'of -improvement will hereinafter appear.

I will 'now proceed to describe my invention in detail, the essential features of whichy will be summarized in the appended claims,

'reference being had to the accompanying drawings, forming part'hereof; wherein- Figure 1 is a side elevation of a lampbracket embodying my improvements; Fig. 2 is an enlarged cross-sectional Aview of a portion of the ,casing ofthe bracket, the cable reel and associated parts being shown in elevation; Fig. 3 is an 4enlanged vertical sectional view of the lrotary connections which' form part of my invention; Fig. 4 is a top plan view thereof; Fig. 5 is anA enlarged sectional plan view, the section being taken On a line 5-5 inFig. 2; and Fig. -6 is a cross-sectional view, the section being taken on a line G-Gn-Fig. 5.

In the drawings Ihave shown a reel 1 upon which is wound a cable 2 carrying eircuit wires 3 and 4 which, by means of rotary connections, consisting of arms 5, 6, 7 and 8, convey current to wires 9 and 10,1' whichin turn are connected to' a lamp Il or other electrical device, such as a fan, telephone, etc. The reel 1 is pivotally mounted upon av base-plate 12, which has secured thereto a.

` the like.

Screw 24, to a block 25, of insulating mateycasing 13 to protect the reel and associated,

parts. rlnhe reel is mounted upon a pin 14 (see Figs. 5 and 6) secured to the plate 12.

The reel 1 is provided with a recess 15 in thebottom Vthereof which contains ya. coil spring 16. The spring 16` is at one end secured to the base-plate 12, the other end of the spring being secured to the hub 17 of the reel 1. The spring 16 willtend to wind the reel, up. The unwinding of the cable will pla ce the spring 16 under tension 4so that whenthe cable is released from itsv connection with the main circuit, it will be wound Y up upon the reel 1.v As will be seen in Fig.

ing end'19 o'f 'cable 1 will rotate'around the pin 14.

In combination (the above mentioned arms 5. 6, 7 and 8.) to connect the wires 3 and' 4 with the'current consumingelement 'carried by the bracket;

which I will designate as an entirety by 22.

"and coperating vwith the 'rotary reel 1, I employ movable connections As will be seen in Fig. 2, the wires 3 and 4 are connected to the arms 7 and 8, respectively, which arms are rotatably mou'nted upon a bushingn 23, the bushing 23 being of insulating material. such as rubber, fiber or The bushing 23 is secured, by a rial,` carried by the reel 1. vThe arms 7 and 8 are insulated one from the other byv a washer 26 of insulating material. but the arm 7 has in contact therewith the arm 6 to which is secured the supplemental circuit wire 10, the wire 9 being secured to the arm 5 which is held in contact witha washer 27,

bearingvagainst the head of the screw 24, by a spring 28, the spring being insulated from the arms 6 and 7 by a washer 29 of insulating material. A s will be seen in Fig. 3, the screw 24 engages the'arm 8l Tienes the arms 5 and 8 will be in circuit with but insulated from the arms 6 land. 7 which are in circuit one with the other.- When the reel 1 rotates, the arm 8 will rotate with it.

Although the arm 7 is free to rotate (that is to say, it is not secured permanentlyl to any otherv part) it will rotate with the reel because of the connected wire 8 which will be stiff enough to-.cause the said larm4 7 to travelwith the plate. As the element carried by the bracket (the lamp 11 for instance) will be fixed, it would be undesirable to carrv the wires 9 and l0 around with the reel. For this reason provide the notata bly mounted arms 5 and 6, which permit the bushing Z3 andpin 24 to rotate, whilethey, the arms 5 and 6, will remain stationary, Vbe cause the said bushing 23 and spring 28 will move within the said arms 5 and 6 when the reel is rotated. ln other words, the arms 5, 6 and 7 are loosely mounted upon the busliing 28, the spring 28 acting to keep' thearms 6 and 7 and arm 5 and washerQ/ infirmcontact and Vat the same time forcing the washer27 against the head of the Screw 24.'

through an opening 34C in the casing 13;

lt will be seen that by the above described construction l 'am able to provide a bracket 4within which a conductor cable can be wound and kept out of the way when not in use. rllhe'said cable can be iinwound and connected to a source of supply in a few moments. During the winding and unwindingv the electrical connection will not be broken, as will b e apparent.

Having now described my invention, what l claim and desire to secure by Letters Patent is:
